YARN-WINDING MACHINE. y

Application filed August 17, 1921. Serial No. 493,014,

a machine for windin yarn and is especially adapted for use wit-i those yarn winding machines adapted for `the production of mops or the like.

One of the objects of this invention is the provision of a machine for winding yarn which is so constructed that it will be automatically stopped whenever a string 0f the yarn which is being wound by the machine breaks. y i

Another important object of this machine is the provision of means whereby yarn is wound in an even regular manner upon a fra-me provided therefor, which frame is' removable from the machine and which yarn is wound upon said frame in a plurality of layers and ywith a plurality of strings of yarn being fed to the frame at the same time. f

Another import-ant object of this invention is the provision of a machine .for winding yarn having mechanisms adapted to automatically stop the same when av sufficient desired quantity of yarn is wound upon the frame inthe machine, which quantity can be predetermined. i Still another important object of this machine isthe provision of meanswhereby the' yarn which is `wound on a lframe in the machine is `placed thereon in such position and in such regular order that itis adapted to be immediately stitched togther and then cut into strands ready to y*be formed into a mop.

Other and further important objects of the invention will be apparent from the disclosures'V in t-he accompanying drawings and following specification.`

The invention (in a preferred form) is illustrated in the drawings and hereinafterY more fully described. l

Figure 10 is a section on theline 10-10 of Figure yFigure `11 is a detail view -`showing the construction of the automatic stop inechanism.y y As shown on vthe drawings-z t The reference numeral t 1 5 .indicates the base ofthe machinev consisting of a rectangular frame with 'supports at each corner thereof. Mountedabove the frame and at a distance slightly behind the same is a support 16 preferably in the form of` a bracket ,extending1 fromca wall or the like upon which is mounted acollapsiblewheelor reel 18 Yadapted, toV support =a skein of yarn 20. This reel 18 is revolvably mounted by means ofan aXle22 removably placed in bearings 24 in the bracket 16. Any .desired number of reels may be fused. Adapted to guide and supportthe strings of yarn 2O as they areunvvound from the reels 18 is a plurality of uprights 26 made of wood or metal set into the base ofthe frame 15, and `attached Hl5 is an arm 54,-supportingV a bracket SOhaving thereon loops 32'for the reception of the a plurality of rocker members 40 each consisting of a pivoted arm having at its end a loop or port 42 through which the yarn passes as shown in Figures 7 and 10 and at the other end of the arm 40 is attached a counterweight 44. These rocker arms 40 are slidably fixed in positionV upon the shaft 38 by having mounted upon the shaft lugs or the like 46 which are heldv in position by set screws 48 in order to maintain the rockers 40 in any desired. spaced position. As shown in the figures, three of these rockers 40 are mounted on the arm 38 but it will be obvious that any number of them may be employed as desired.

A contact point 50 is provided on each rocker arm 40 for coaction with a corresponding point on the rod 36 when the rocker arm`40 has been thrown up into the position lshown in the dotted'lines in Figure 7 by reason of the action of the counterweight 44 on account of the releaserof the arm by the breakage of the string of yarn 20. An additional loop 52 is provided at the lower end ofthe bracket 30` to additionally guide the string 20. rlhe bracket 30 and the plate 34 are all fixed by means of screws 53 to the slidable rod 54 which extends longitudinally across the top of the machine and the rod 36 is insulated from the remaining parts of the bracket by means of insulating washers 55 as shown. The supporting'rod or arm 54 is adapted to be reciprocated across the top of the machine by means of a heart-shaped cam 56 cooperating with a projection or roller 58 mounted in the rod as best shown in Figures 2 and 3, and the rod itself is slidably mounted in suitable bearings 57 on thel frame 15 as shown. The cam 56 is eccentrically mounted on a vertical driving shaft 60, this shaft in turn being revolved by means of a gear 61 coacting with a worm wheel 63 on a Vhorizontal shaft 62 (Figure 5) which shaft 62 is in turn driven by a similar gear 65 thereon (Figure 2) which coacts with a worm 64 on the main driving vshaft 66 (Figure 3), which is driven by a pulley or the like 67 having fixed thereon a clutch member 68, the operation of the clutch being controlled by a lever 69 (Figure 2). This lever 69 is normally held in retracted release position by means of a spring 70, but it has fixed thereon a hook attachment 71 coacting with a similar hook on the end of a soft iron rod 7 2 pivoted at 7 3 to a bracket on the frame 15 of the machine and having its other end spring-held in downward position by means of a spring 74. Mounted immediately above the spring-held end of the rod 72 are a pair of electro-magnets 75 which cooperate with the rod 72 to draw the same into an upward clutch releasing position whenever a circuit is closed through them.

The end of the driving rod 66 terminates in a c form of lathe arrangement and is mounted in a bearing 76. Mounted in a similar aligned bearing 77 at the other side of the machine is a rotatable spring-pressed cooperating member 78 having a handle or wheel 79 by which it may be manipulated. This lathe arrangement is adapted to rotate a frame 8O rectangular in form, and upon which is wound the three strands of the yarn 20 delivered from the reels 18. The construction and arrangement of this frame 8O is more fully described in my co-pending application for process of making mopsf7 i Serial No. 493,012 filed Aug. 17, 1912.

Mounted Von the rearwardly extending end of the shaft 62 is a beveled gear 82 adapted to cooperate with a similar beveled gear 83 mounted on the bottom of the vertically extending screw-threaded shaft 84 as best shown in Figures 1 and 11. An upwardly extending rod 85 is mounted parallel to the screw-threaded shaft 84 and slidably positioned upon said rod is a block of insulating material 86 held in position thereon by means of a set screw 87 as best shown in Figure 9. A metal member 88 is fixed to the insulating block 86. Adapted to cooperate with this contact member 88 is a corresponding contact member 89 mounted upon a movable block 90 slidably mounted on the rod 85 and provided with a Vhalf round screw-threaded section 91 as best shown in Figure 8. This half round screwthreaded section 91 is internally threaded and is adapted to cooperate with threads on the rod 84. A handle 92 is pivoted at 93 on the block 90 and is held in outward position by means of a coiled spring 94 for the purpose of maintaining Vthe screwthreads in the half-round block 91 in contact with their corresponding threads on the shaft 84. A wire 95 leads from the insulated rod 36 to the magnet 75 and from thence to a battery' 96 which has its otherl terminal grounded to the machine at any convenient point. The contact points 50 on the rockers 4() are not insulated from the frame. Another wire 97 also leading to the magnet 75 and the battery 96 is connected to the insulated contact member 88 which cooperates with the contact member 89 grounded to the frame of the machine.

The operation is as follows:

A collapsible reel 18 is first inserted into a skein of yarn 20 and then threaded through the loop in the support 26, 28 as shown in Figure 1 whereby the yarn 20 is held in position ready to be reeled off to the frame 80. Three of these reels 18 are provided in the preferred machine, each having a thread 2O leading therefrom. Each of these threads 20 passes through a loop in the end of an upright member 26, 28 as shown in Figure 1 and thence to a loop 32 in the bracket 30, as shown in Figures 1 to 7. The yarn is then led over the rod 36 and passed through the guide members 42 on the end of a rocker 40, after which it is led through a loop 52 as shown in Figure 7, to properly guide it onto the reel 80. The reel 80 is rotated by means of its connection with the main driving shaft 62, the speed and timing being properly adjusted, and at the same time the supporting arm 54 holding the brackets 30 and 34 with their connected members in position is reciprocated back and forth across the machine to a predetermined degree, (in this case 5 inches) by means of the action of the groove. in the heart-shaped cam 56 cooperating with the projection 58 upon the arm 54. This results in the forming of a plurality of evenly placed layers of the yarn 20 on the reel 80. The rotation of the shaft 62 also causes a rotation of the threaded rod 84 by means of the beveled gears 82 and 83 and this results in an upward movement of the member 90 on the threaded rod 84. vThe contact member 88 on the block 86 is yso positioned that when a predetermined amount of yarn has been wound on the reel 80 the member 89 will contact with the lpoint 88 causing a making of the circuit in the wire 97 which actuates the magnet 75 which thereupon acts to draw up the free end of the arm 72 against the tension of the spring 74 disengaging the hook 71 and allowing the spring 70 to retract the arm 69 thereby releasing the clutch 68. In this manner the operation of the machine is automatically stopped and the amount of yarn delivered to the reel or frame 80 is controlled.

In case one of the threads 2O breaks the rocker 40 will be immediately released and its counterweight 44 will throw it upwardly into the position shown in the dotted lines in Figure 7 and the contact point 50 will come into cooperation with its corresponding contact point on the insulated rod 36 thereby making a connection through the wire 95 to the battery 96 and through the magnet 75 which will operate to release the clutch 68 in the same manner as has heretofore been described.

It will be seen that thevoperation of this machine is entirely automatic, the same being controlled both as to the amount of yarny fed onto the reel or frame 80 and also automatically stopped upon the breakage of any of the strings 2O by means of the electrically arranged mechanism and Contact members and that waste of time and consequent loss of material due to breakage of the yarn 2O is entirely eliminated, and further an automatic regulation of the amount of yarn to be fed to the frame 80 will be readily accomplished. Suitable switches may be provided for controlling the current, and the member 90 may be readily reset by gripping the handle 92. L

I am aware that many details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon,

otherwise than necessitated by the prior art.

I claim as my invention:

In a yarn winding machine, a winding reel, a driving shaft therefor, a rotatable member operatively connected to said shaft, a clutch for controlling said shaft, solenoid operated means for releasing said clutch upon the breaking of a yarn, and a contact element adjustably mounted upon said rotatable member and movable relative thereto during the rotation thereof for: effecting an electrical connection for energizing said solenoid for releasing said clutch after a predetermined amount of yarn has been wound.

In testimony whereof I4 have hereunto subscribed my name in the presence of two subscribing witnesses.
